They are usually a good resource for this type of information.

Use eucalyptus or neem oil
Both eucalyptus and neem oil will kill ticks on contact.

To use these essential oils to get rid of ticks, combine 4 ounces of purified water into a spray bottle, along with 30 drops of your carrier oil of choice. Shake well and spray anywhere you want to kill ticks.

Two suggestions.

Good ideas here.
Create a Tick-safe Zone


Have someone else check body areas you can't see.

I have a tick key but fortunately have not had to use it. In most sporting goods sections, I think.

CDC says:
https://www.cdc.gov/ticks/removing_a_tick.html
Avoid folklore remedies such as “painting” the tick with nail polish or petroleum jelly, or using heat to make the tick detach from the skin. Your goal is to remove the tick as quickly as possible–not waiting for it to detach

Both CDC pages link to pdf files with more info.

to keep them off you but I've never tried it.

On an episode of Homestead Rescue they brought in a certain type of chicken that eats ticks. I bet Google could help you find them

might have been able to learn that except hawks got to all our chickens.

course they'll eat all the plants eventually, but...

them in and out of an area and collateral damage can be minimized to a large extent. Chickens prefer bugs and worms over plants, generally. But they are bio-cultivators.

get some guinea hens, mow wide paths through all your tall grasses, tuck your pants into your socks, use Off! spray... that's about all i got. You'll never rid your yard btw, best you can hope for is to keep them off you. Eating raw garlic has always worked best for me... but not necessarily everyone else around me.



Good Luck.

it's made of cedar oil and is an incredible repellent. I am using the lemon grass scent, but found that it has the dreaded laurels, but i spray it on my clothes.

(finding survey markers, new fencing for donkeys/goats). I've had to pick off ticks in the darnedest places! The only thing I've had to work at all is Off/Deep Woods.

That is where the disease was named. My recommendation is creating cedar mulch walkways. Ticks seem to stay away from cedar.
